These strange brakes were on a old Schwinn. The bike was very entry level looking and didn't interest me but I don't ever remember seeing brakes quite like these.

Rollercams, you should have bought it if the price was right. Now looking at the fork, it was probably a Cimarron.

Those are Suntour XC Sport Roller Cam brakes. The design was by MTB pioneer Charlie Cunningham. They used U-brake mounts but a very different mechanism.

The bike was not entry level. The lugged unicrown fork, black chrome, and Roller Cams were specced on High Sierras and Cimarrons in the mid-80s. So it was either Schwinn's top tier or 2nd from top tier MTB.

Its probably still there I can go back in the morning and see. I think it just said Seirra on it. It looked like it was a pretty big bike. I didn't see a price and some of the stuff there is overpriced but not always.

I believe his name was Charlie Cunningham.Richard Cunningham founded Mantis Bicycles.I had a Schwinn High Sierra with these brakes, they worked very well.

I have no idea what to offer for it or what to do with it if I buy it. The wife who is usually very tolerant of my bike habit didn't seem too pleased with me for suggesting another look. I'll probably do it anyway :)

Typo on my part. Thanks for catching. I've recently been looking at some of Second Spin's Mantis restorations so had Richard on the brain.

Well I went back up there and that vendor has already left. He will likely be back next month with the same stuff. I'll try to check then.

Could be one of these High Sierra bikes.

Those brakes are sought after.

Hmmm... I have them on an old Cannondale. If it is just the fork, that could have been swapped. if it is the fork and frame, then it would be original.

They are not compatible with later canti brakes, unless, perhaps you change wheel sizes.

It was original both brakes were the same and it looked like the High Sierra in the above picture except it was black. I'm not sure if it said Sierra or High Sierra. It was pretty dirty and a little rusty. I'll see if he has it next month. We have trades days every 2nd Monday and there is a lot of the same stuff there month after month.
